MACHINE FOR FORMING UPPERS 0F BOOTS AND SHOES.

Application filed August 5,

To all 11:15am it may concern:

Be it known that'I, Kant EXGEL, a subject, of the Emperor of Germany.residing at Revere. in the county of Sult'oll: and ('onnnonweaith-ofMassachusetts, have invented certain Improvements in Machines lulForming tippers of Roots and Shoes, of which the following description.in connech is a specification. like reference characters on the'drawingsindicating like parts in the several figures. i

This invention relates to ipachinesfor use in the manufacture of shoeshaving ontturned uppers. Shoes of this type-are commonly known to the t'ade as stitch-downs the upper of a shoe of this type being attached tothe sole by stitches. or other fastenings. which are passed through theoutt-urned portion of the upper and through the sole.

Although the stitch down shoe is one of the older types of shoes,the'manufaeture and commercial exploitation of this shoe, particularlyin the better grades. has not been undertaken upon a large scale up tothe present time. This has been due largely to the fact that theadvantages to be gained in manufacture of this shoe by reason of thesimplicity of the sole-attaehing operation have been more than(ounterbalancetl. by the difficulties attending the preparation of theupper for this operation. Many methods have been devised for preparingthe up pet's of such shoes for the $Ul8-tll'titt'illfif operation. Thegreater num er of sum methods involve shaping the upper over theSpecification of Letters latent.

iast in approximately the usual waythe ehie -.lill'erenee being; that inthe ease of flit.etllfit-(ltizfil shoe upper the upper is turned outaround the bottom edge of the last instead of being turned in. Thesemethods in practical application hare .oeen found as a ruleunsatisfactory. their employment resulting either in a pooi-l y-s;=:iped upper or in a poor]y-tormed flange for the attaehmenfot' the sole.They are al o waste- 1 ful of material.

One of the chief dittienlties atteudi E In! the sole-ataching operationby the simple lasting method is that of forming a smooth and properlycurred out-turned flange. 331911 En-mg nothing upon the last which xvii?aid Patented July M5, 1911.

t in the formation of this flange or to With-i1 the flange may beattached alter 't has b en formed. Another dillienlty to be )YOII'Uhipis that of properly gathering in the leather about the toe portion ofthe upper to form the bulge over the flange at the toe. whi h isdesirable both for appearance and H ll.- fort. and atthe same timeleaving; this partof the upper smooth. This dillieulty i ircreased inthecase of the forum: n of a stitehalown upper by the Iltt'OMilI) of foruringrat the same time abom the toe a smooth flange. or at: least a flangelying in one plane.

The purpose of the present invention i t provide a mechanism which willobviate the ditlicult es hereinlwfore pointed out and whielfiwill formfrom a flat toe blank of leather or other flexible material a prop-91-15 shaped toe. ha ing an out-turned flange for sole-attachingpurposes. The invention has also for its aim the aeeomplishment of thispurposeby a exunparatirely simple mechanism which in its operationutilize a novel method of forming the toe i'or'a shoe upper. this methodbeing (thetaa and claimed in U. S. Letters Patent No. 947.595, datedFeb. 1, 191.0.

The in entionaimsfurther to prmide a mechanism for use in themanufacture of stitch-clown shoes which combines ellieient means forshaping the toe portion at a stitch-down shoeupper. together withlikewise etlieient means for forming upon the upper an out-turnedflange. said two means operating in such manner that neither caninjuriously ait'eet the work of the other. 7

Another object of the invention is to provide a mechanism of the kindjust descrioed in hich the two aneans t'tl ill\rllti"ill sreh mannerthat 'e u-h aids in the perforimmce of the work oi the other.

A further object of the in ention is to provide a met'lr ixm of the kind\l( 'l'll r(l which in ope a n will have no tend-":icy

in tent or unduiy strain the upper and hit-h will .nrlude means tormoving any e \'('e S ot' malerial from the region or regions where itmar m'vm to the region or regions where it needed in the ope 'atioim'ifshapingtbe toe and forming the out-tn 'ned flange.

In the illnst rated embodiment of the invention it will be noted thatlast s hz:\e been dispensed with in the toe shaping operation,

the place of the last being taken in theconstruction shown by a former,preferably of "metal so that it may be :readily heated,

which former is removed from the shaped toe as soon as the material isset in its proper form.

I twill be evident, therefore, thata further object 'of the invention isthe provision of means for shaping the toe of a stitch-down upper whichwill avoid the necessity for lasting the upper in the usual way. An.

obvious advantage of such a mechanism is the saving effected in bothlasts and lasting tacks.

All methods of lasting in the usual way with wooden lasts and tacksinvolve considerable -Waste of upper material which it is necessary totrim off after the upper has been lasted. This is especially true ofsome much material as is actually necessary to form the upper and itsflange. In the construction illustrated, this inventive idea is carriedout by providing means which gages the flange upon the upper, incombination with means which properly shapes the upper while it isheldby the gaging means. It is obvious that if it were attempted to shape anupper in this way by gaging the flange upon a flat blank and thenrigidly confining the flange while the upper shapmg means operated uponthe unconfined.

ortion of the blank, there would be great iability of tearing thematerial, especially if it were comparatively non-extensible mamateriallike patent leather. It is further obvious that this liability to tear'wouldbe increased if, in'such a combination, it were attempted to bulgeout the toe porton over -the flange in order to form a crease around thebottom of the toe.

A further important feature of the invention, therefore, is theprovision of means for clamping the gaged flange portion of the blank tobe formed or molded in such manner that portions of the flange, which,in the upper as finally shaped orvmolded,

would have an excess of material, may bemoved toward other portions,which, owing to the shape of the upper, would havea deficiency in theamount of material necess'ary for the proper operation of'the shapingmeans. It is obvious that such movement of the flange portions of theblank to be formed or molded will also have a tendency to gather in thematerial of the blank along the flange line and thus cause a fullness ofmaterial upon each slde of this line,

blank of finished material maybe clamped in such manner that clampedportions of the blank may be moved relatively to the clamp.- ing meansin defined directions without scratching or tearing the finished side ofthe blank In the preferred construction this feature is embodied in aclamping means having a smooth clamping surface adapted to engage thefinished side of the toe blank and having a roughened clan'iping surfaceadapted to engage the unfinished-side of the toe blank, the roughenedsurface being formed upon apart movable in the plane of the clampedportion of the blank whereby the said clamped portion may be, moved withthe'movable part of the clamping means over the smooth clamping surface.

- At the forward end of a base or frame 2 which is adapted to be mountedupon a bench or othersuitable support is an enlargement 4 having, in theconstruction shown, an approximately U-shapcd recess and constituting anelevated support for a plate 6 which forms the stationary member of aclamping'device for clamping a toe blank. The platetiis smooth on itsclamping face and is provided with a recess-ovcr lying that in thesupport 4 but somewhat smaller, so that its inner beveled edge projectsover the recess in the'support 4; The recess in the plate 6 has thecontour desired for the bottom edge of the toe to be formed.

A movalji'clamp member 8, adapted to cooperate with the clamp member 6,is

mounted upon rods 10 passing through" openings in the'member 6 and inthe support 4 andconnected at their lower ends by a cross piece 12, fromthe ccnter of which extends a rod 14 to a treadlc 16 pivoted upon asupport 18 which may be mounted upon the 'flo'or. By depressing thetreadle 16 the clamp member 8 may be brought down into engagement withthe clamp member 6, or with the blank lying upon the member 6. A toothedplate 19 adjacent to the path of the trca'dle is adapted to lock thetreadle and i i 't t with it the clamp member 8 in depressed position.The clamp member 8 is provided with neth or corrugations on its underside in order that it may firmly grip the mater al of the toe blank,these teeth or corrugations in the illustrated embodiment of theinvention being carried by plates mounted upon the member 8 withprovision for movement relative thereto. Of these plates, those ada tedto grip the side portions of the toe or the portions of the blank whichare to form the flange along the sides of the we. are indicated at 22.'12 upon the drawand are each provided with threaded pi; -l adapted totravel in slots in the clamp member and confined in said slots by nuts Athird toothed plate is mounted upon the clamp member 8 in position togrip the forward part of the toe blank. this plate 30 being connected tothe member .5 by. a headed screw traveling in a lot 3% in said member.It will be noted that these plates have movement only .in the plane ofthe clamping means,the side plates being so guided in their slots thatthey move in converging paths toward the front of the toe blank, and thefront plate being guided in its slot and by its contact with the sideplates so that it moves rearwardly with a clampedportion of the blank.

The side plates are preferably kept nor: mally in their rearmostpositions by springs 36 and 38. the spring 36 being; attached at itsrespective ends to a pin it) on the clamp member 8 and :1 lug -12Oil'lllt righthar-d plate 22. The spring 38 is attached to a similar pin40 upon the clamp member 8 at its rear end but at its forward end it isattached to one arm of a lever 41, pivoted at 16 upon the clamp member 8and having its other arm pivotallv connected with the plate 30. Anotl'set portion l-S upon the lefthand side plate 23 is adapted, as theside plate 22 lllU'i'Bh forward. to engage the outer arm of 1b:- leverand cause it to rotate about its pivot. l thereby moving in a rearnarddirection the front plate :ao.

Movement longitwlinaliy oi the clamping Inechanian may be impaited tothe carriage it and the former so by means of the lever 60 pivotallymounted .Lll ears '2 rising from E outer edge of the toothed portion ofthe the base 2. The lever 60 has an enlargement about its pivot. saidenlar ement being provided with circular shoulders ecerntric lo thepivot of the lever, and links (3% connected at one end to. the pivot 53have openings at their other end into which the shoulders upon the lever(30 fit. Rotation of the lever (50 about its pivot therefore impartslongitudinal movement to the carriage 54, forward movement beingimparted to the earriage when the Ieveris depressed and rearwardmovement when it is 'aised.

The toe former 50, when not in use, is adapted to rest upon a steam pipe(36. shown in section in Fig. 3, which steam pipe passes through thesupport 4: below the clamp member 6 and is adapted to lltntl the supportand its attached clamp members. A depressing lever 68 pivoted at 70 in aforked post 72. integral with the support l at its forward end, carriesan engaging block Tl adapted to engage and depress the toe former 50 asit rests upon the toe blank clamped between the clamp members 6 and 8.The action of the depressing lever is 01d temporary. the toe former 50after it has been depressed sufiiciently by the depressing lever beingmoved forward by the lever (30 until its forward end lies under theoverhanging part of the clamp plate 6 by which it is kept in itsdepressed position. s

The shape of the recess in the clamp plate (3 determined not only by thestyle of the shoe for which it molds the toe, but also by the (litteringcharacteristics of the right and left shoes of a pair. If. therefore, a.toe is to be molded which is not symmetrical, two molding devices arepreferably employed, one for the toe of a right shoe. and the other forthe toe of a left shoe. of a pair. =Furthermore, it is advantageous toprovide several of these molding devices for each operator, in orderthat the former may be allowed to remain in the toe fifte! it has shapedit until the material of the too has adapted itself to, or set, to itsnew form.

The operation ofthe mechanism lrereinbefore described is as followsz Asuitable toe blank, such. for example. as that shown in Fig. 4. .havingin position its lining and stiff material to form a box too, is clampedalong its outer edge between thernunp members 6 and S. the material ofthe blank when clamped lying" approximatelyall in one A lldnlk' 5 plane.As the blank is placed upon the loner clamp member 6 in position to beclamped. the width of the flange to be form-- ed is gagrt-d from theinner edge of the member (3 in any suitable way, as, for example, byextending the edge of the blank to the plates 2;. 22 and 3t), and theclamp member is then-moved down to engage the inner. -side of the blank.the outer or finished side lying against. the smooth surface of theplate 6. The toe former 5t) and frame 56 2 have previously been raisedabove the clamp;

ing mechanism. The blank having been clamped, the toe former 5G is nowbrought down upon the upper surface of the blank and the depressinglever 68 is swung about portions of the clamped material along the sidesof the toe blankwill cause the plates 22,22 to move forward with the toeformer.

Thismoveinent of the plates 22, 22 will effector .permit the forwardmovement of the portions of the flange along the sides of the toe whichare held by said plates, these portions moving freely over the smoothplate 6. As the left-hand plate 22 moved forward with the toe former,the engagement of its ing witlf'it the clamped between it and the plate6. Should the plate 6, the lnncrsole being of such size offset part 48with the lever -14; will cause the front plate 30 to move re'arwardly carryortion of the toe blank the side plates 22, 22 for any reason fail tomove forward under the pull of the .ma-

terial, due to the action of the toe former 50,- the pushers 58 upon thefront of the frame 56 will engage their rear ends and push thempositively forward.

It will be noted by an inspection of Figs. 2 and 3 that the rearwardmovement of the front toothed plate 30 will cause some of the materialclamped bv it to be moved so that it can be pulled over the edge of theplatefi by the forward movement of the former and thus be used informing the bulge at the front of the toe over the flange. It will befurther noted by an inspection of Fig. 1 that the forward movement ofthe slide plates .22, 22 and the rearward movement of the .Th isgathering in or puckering of the material-in this region and the movingof the material held by the. front plate 30 into a position where it maybe utilized in formingthe bulge facilitates the proper shaping of thetoe, and tends to equalize the strain onthe different parts of the blankin the toe forming operation'and particularly assists in preventingundue strains upon any part of the clamped margin of the blank. Theposition of .the eccentric shoulders upon the '-ever 60 is such withrespect to the pivots of the lever that when the lever is depressed topush forward the former 50, the lever holds the -f0rmer in its forwarlposition until it is again actuated to withdraw the former. The formeris thus held locked in i s depressed position through the action of withthe under side of the plate 6.

The material of the blank is preferably tempered before it is operatedupon by the mechanism hereinbcfore described, although this is 'notessential to the successful operation of the mechanism. that the heatingmeans is so arranged that it heats the clamping means, and that it alsoimparts heat to the material of the toe while the toe former is lockedin its depressed position during the toe forming operation. The insideof the toe blank and the adjacent sides of the toe stiffener and toelining are preferably provided with cement, so that they are bothpressed into shape and cemented together in the toe forming operation.

After the toe has been allowed to set to its new form while the formeris locked in its depressed position and while the flange is held betweenthe clamp members by the engagement of the treadle l6 .vith the plate19, the former is withdrawn, the treadlc is released, and an innersole,provided with cement along the edge of its inner face, is laid upon theflange of the toe lying upon that its edge lies flush with the outeredge of the flange. The clamp member 8 is then depressed sufliciently topress the innersole firmly into en agement with.the out-turned flange.The formed toe with its attached innersole is then removed and theinnersole and flange and further fastened together by stitches. a

the lever 60 and through its cngagcment It will be noted It is obviousthat with material which maybe stretched considerably, a toe shaped likethat shown in Fig. 5 may be formed with mechanism of this typeinwhich nopart of the clamping surface is movable in its own plane. It is alsoobvious that the relative movement of the clamp and the toe former whichcauses the bulge of the toe over the flange may be effected in otherways, as, for example, by providing a mov-- able clamping means. Theinvention is not limited to the number of movable clamping plates, shownnor to the D tions of movement illustrated, nor is it limited to aconstruction in which the outer edge of the blank is engaged by movableplates. It is obvious that some of threadvantages ofthe constructionshown might be gained in a construction in which only the frcint platewas movable and in which the side plates were stationary or vice versa.
